# Runout Sensor Adapter

This is a filament runout adapter that allows a bowden tube from a dry box to be connected directly to the Elegoo Centauri Carbon.

The only part you'll need is a "pc4-m10" pneumatic fitting (with the passthrough hole).

Thread the fitting into the printed part, then snap the adapter on over your filament sensor.

Then insert the bowden tube all the way to the sensor.

After that, simply enjoy your dry filament straight out of the dry box.
